Description

Technical Field

[0001] The utility model relates to the technical field of drilling positioning, in particular to a drilling positioning device. Background Art

[0002] The curved tunnel system is a common tunnel design, characterized by an arc-shaped or nearly semicircular cross-section. Curved tunnels have a large arc radius, which provides good lateral stability. Curved tunnels are suitable for areas with relatively stable geological conditions and low atmospheric pressure. Anchor bolts in curved tunnel systems play a crucial role in maintaining rock stability, controlling surrounding rock deformation, and leveraging the rock's self-supporting capacity. Drilling is the first step in anchor bolt construction, and the direction, angle, and depth of the drill holes should be precisely controlled according to design requirements. For curved tunnels, the anchor bolts should be drilled essentially perpendicular to the tunnel excavation face.

[0003] The angle needs to be controlled during drilling. The existing positioning device has poor structural flexibility, a small adjustable range, and large errors, which causes the anchor rods to be unable to be perpendicular to the tunnel excavation surface and poor force, posing certain safety hazards to the structural safety of the entire tunnel.

[0023] It should be noted that the utility model places the side support frame 1 in the arc-shaped tunnel, and then fixes the bottom to the bottom. The upper end of the side support frame 1 is fixed by screws, and the vertical slide bar 11 slides on the outside of the limiting beam 3. The horizontal position of the positioning cylinder 14 is adjusted by the vertical slide bar 11 and the moving box 12. After adjusting to the appropriate position, it is fixed, and then the vertical height of the positioning cylinder 14 is adjusted by sliding the moving box 12 on the outside of the vertical slide bar 11. The positioning cylinder 14 is driven to rotate around the connecting shaft 15 by the driving part, so as to realize the elevation adjustment of the positioning cylinder 14.

[0024] See also Figure 1 、 2 As shown in Figures 3, the side support frame 1 is a U-shaped structure, and the lengths of the two ends of the U-shaped structure are different. One end of the top of the side support frame 1 is fixedly connected to a fixed connecting plate 2, and a positioning nail 10 is detachably installed at the bottom of the side support frame 1. A plurality of fixing plates 7 are fixedly connected to the bottom of the side support frame 1, and an adjusting screw 8 is threadedly connected to the middle part of the fixing plate 7. The bottom of the adjusting screw 8 is rotatably connected to a self-locking wheel 9.

[0025] It should be noted that the utility model adjusts the height of the self-locking wheel 9 by adjusting the rotating adjusting screw 8. When the bottom of the self-locking wheel 9 is lower than the bottom position of the side support frame 1, the entire setting is moved by the self-locking wheel 9. When the side support frame 1 needs to be fixed to the ground, the rotating adjusting screw 8 will raise the self-locking wheel 9, and contact it with the ground through the positioning nail 10, so as to fix the side support frame 1 to the ground, and then the fixed connecting plate 2 is fixed to the tunnel slope through other fasteners such as expansion nails, so as to provide stable support for the positioning cylinder 14.

[0026] See also Figure 1 、 2 As shown in Figures 3 and 4, both ends of the vertical sliding rod 11 are fixed with a sliding sleeve 5, the internal sliding connection of the sliding sleeve 5 is a limiting beam 3, both ends of the limiting beam 3 are fixed with the side support frame 1, and the outer side of the sliding sleeve 5 is threadedly connected with a positioning bolt 6.
